2 Claims. (c1. 415-11) This'invention relates to a collapsible stand.

An object of the invention isto'provide such a stand comprising a tray-like membenand a collapsible. support member therefor.

Another object is to provide a support structure of the kind described having leg members pivotally associated by novel means adapted to hold the leg members in triangular relationship for effecting mutualsupport thereof.

Another object is to provide a stand of the class described in which the leg members may be eliectively associated with the tray portion to preclude collapse of the structure from operative position.

Another object is to provide a collapsible stand simple in structure and operation.

These and other objects are attained by the means described herein and illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective View of the collapsible stand of this invention in operative position.

Fig. 2 is a fragmental view of the central portions of the support structure of this invention in collapsed position.

Fig. 3 is a cross section view taken on line 3'3 of Fig. 2.

Fig. 4 is a cross sectional View taken on line 4-4 of Fig. 1.

The support structure of the present invention comprises three leg members, 5, 6, and '7, each in the form of a flat bar bent intermediate its end to provide sections 8, 9 and 10 disposed at substantially right angles with the remaining portions of the respective bars. These leg members are adapted to be associated by a pivot block 11 of substantially equilateral triangular shape in plan, as clearly seen in Fig. 3. The three sides 12, 13 and 14 of the pivot block are each provided with a diagonal square-cut way 15 of a width greater than that of the individual leg members. These ways 15 extend from top to bottom of the sides of the block 11 and at similar angles and in similar directions relative to their respective sides. I

The intermediate sections 8, 9, and 10 of the leg members are each adapted to be pivotally mounted on the block in one of said ways, by means such as the pivot studs 16, projecting through the leg members and into the block '11 to be suitably secured at their inner ends '17 which are made accessible by means of a central bore 18 provided in the pivot block. A look washer 24 between the head of stud l6 and block 11 serves as an expansion spring to preclude looseness of the leg member.

The ways v11 are adapted-to limit pivotal movex ment of the leg members. When the leg members '5, 6,- and 7, pivotally mountedin themanner described, aredisposed in parallel relationship such as seen in- Fig.2, the support structure is in its collapsed inoperative position. I The leg members may be swung pivotally from paral lel relationship into divergent operative position. At this time said leg members project in upwardly and downwardly divergent relationship above and below their connecting means, i. e., the block 11. In this position,the side edges of each of the intermediate sections 8, 9, and 10, abut diagonally opposite corners 19 and 20 of the ways 15. The lower ends of the leg members are adapted to be placed upon a supporting surface in triangular mutually supporting relationship. As seen in Fig. 1, the bottom ends of the leg members may be turned upwardly to pro vide the feet 21. It will further be seen that are disposed so as to present their faces rather than their edges toward one another. The upper ends of the leg members, in the operative position of the structure, are likewise disposed in triangular relationship and are adapted to have a tray-like member 22 placed thereon.

vIt will be understood that the tray member 22 may be replaced by other suitable means such as a table top container or the like. It is preferable that the top member utilized be provided with adown turned edge in order to emciently cooperate with the support structure of this invention. In the present illustration, the tray is provided with a down turned beaded edge. It

will be seen that the upper ends of the leg members, due to their particular formation, are adapted to be disposed against the under surface of the tray member and to lie flush against the beaded edge 23 of the tray. In other words, the

upper ends of the leg members have theirfull width in contact against the beaded edge; 23 so that there is a firm relationship of the set up structure adapted to v preclude accidental displacement of the tray.

' the outer or end portions of the leg members The device is simple in its parts, construction,

and operation and eflicient in use. Modifications structure comprising three leg members each formed of a flat bar bent intermediate its ends to! provide a section disposed at substantially right angles with the remainder of the bar, a pivot block of substantially equilateral triangular shape in plan, the three sides of said block being each provided with a diagonal square-cut way of a width greater than that of the leg members, said ways extending from top to bottom of the block sides at similar angle and in similar directions relative to their respective sides, the intermediate section of each of the leg members being pivotally mounted on the block in one of said ways to permitswinging oi the leg members from parallel collapsed relationship into divergent operative position wherein the side edges of each of said intermediate sections abut diagonally opposite corners of the associated way, the lower ends of the leg members in this position being adapted to be placed upon a supporting surface in triangular mutually supporting relationship, the upper ends of said members being likewise disposed intriangular relationship and being adapted to havethe tray-like member placed thereon with said ends disposed flush against the downturned edge of said member.

2. A collapsible stand comprising a tray-like member and a support structure therefor, said support structure comprising a pivot block of equilateral triangular shape in plan the three sides of the block being each provided with a diagonal square-cut way, said ways extending from top to bottom of the block at similar angles and insimilar directions relative to the respective sides of the block, and three leg members each consisting of a bar pivotally mounted intermediate its ends on said block in one of said ways, each bar being of a width less than that of its associated way whereby the bars are adapted to be swung from parallel collapsed relationship into relatively divergent and operative'positions with each bar contacting diagonally opposite corners of its associated way, the bars in this position being adapted at one end to be disposed on a supporting surface in spaced triangular relationship, the other ends of the bars being disposed in similar relationship and adapted to have said tray-like member placed thereon.
